養耕共生和都會農場可以創造綠色就業嗎？ By Charles Redell報導, 2011/9/16
In the wake of President Obama's jobs speech last week, the national conversation is intently focused on growing jobs -- and particularly green jobs -- in the weak economy.
This week, we saw a new twist on green jobs, and one that promises something of a Holy Grail of sustainability: Creating jobs to grow sustainable food products at an economically viable scale that will be consumed in the local foodshed.
That's the pitch from the Recirculating Farms Coalition (RFC), which launched earlier this week. The group says the type of farms and farming it promotes can achieve those goals and more, including urban job creation.
The coalition is promoting sustainable, closed-loop farms that grow local, fresh food and, it says, create green jobs using clean, recycled water in place of so…
Taiwan Genetic Engineering, Luminous Angelfish
The most recently created fluorescent fish are angelfish - the biggest and brightest transgenic glowing fish in the world so far.
Taiwan's largest exporter of ornamental fish, the Jy Lin Company, says it has successfully inserted a fluorescent protein gene into the reproductive organs of the fish. It allows them to produce glowing offspring.
The company says its new breed of fish took more than three years and approximately 10 million Taiwan dollars to develop because the reproductive cycles of medium-sized fish are harder to control than their small-sized counterparts.
The angelfish are members of the biological family Cichlidae.
Cichlids make up the majority of fish seen in most aquariums. "With the medium-sized cichlid fish, its biological cycle cannot be controlled by artificial lightings. Plus the low number of fertilized eggs makes the collection of fertilised eggs a challenge - it will take a very long time with the …
